xvii w SPECIES OF CHIMPANZEE $79
which a part is reproduced in Professor Huxley's essay referred
to below,1 the Apes, which correspond roughly in their appearance
to Chimpanzees, are represented as being captured by the device
of limed boots, which the Apes are putting on. This idea has
been subsequently imitated and acted upon. A little later, Andrew
Battel wrote of the Pongo and of another creature the Engeeo.
This latter, whatever may be the case with the former, is in all
probability the Chimpanzee, since the word 'JS~chego, now applied
to those creatures, seems to be the same -word. From this seems
also to be derived the sailor's term " Jacko." Whether there are
or are not more than one species of Chimpanzee, is a matter
which has exercised and perplexed naturalists. That there are
plain differences of external features, at any rate between in-
dividuals, is perfectly clear. We are justified in recognising
three forms, but the question of their specific distinctness may
for the present be held in reserve. The commonest of these is
the variety known as -4. troglodytes. This is frequent in mena-
geries, though the specimens on view are nearly always young
and small. The face and the hands are flesh-coloured, and the
ears are very large. The black hair gets a reddish tinge on the
flanks. The second variety is that which was termed by du
Chaillu Troglodytes Tcooloo-Jcamba. This animal appears to be
also the T. aubryi of MM. Gratiolet and Alix,2 and to be identical
with two Apes known by the names of " Mafuca " and " Johanna." 3
The former of these was exhibited in Dresden, the latter at
Messrs. Barnum and Bailey's show. The two animals have been
carefully studied. They differ from the common Chimpanzee by
the dark colour of the face, and in the case of Mafuca the ear
was G-orilline in form. So too was the ear of A., aubryi, while
Johanna has a larger one. These features have led to the sug-
gestion that the Elooloo-kamba was the result of a mesalliance
between a Gorilla and a common Chimpanzee.
It has at any rate been stated that the two Anthropoids do
go about in company; but there seems to be little doubt that
there is no question here of a hybrid. Dr. Keith's careful
studies* upon Johanna have demonstrated the impossibility of
